(6y - 11)(6y + 11) = ay
² - b |use (a - b)(a + b) = a² - b²
(6y)² - 11² =ay² - b
36y² - 121 = ay² - b |add b to both sides
ay² = 36y² - 121 + b |divide both sides by y² ≠ 0
a = (36y² - 121 + b)/y²
Answer:
h=v/πr²
Step-by-step explanation:
v=πr²h
v/π=r²h
v/πr²=h
Answer: 44%
Step-by-step explanation:
There are 25 squares in the rectangle. This means that the percentage of each square is:
= 1/25 * 100
= 4%

= 11 * 4%
= 44%
